The thermal storage performance, cost, and stability of phase-change materials (PCMs) are critical factors influencing their application in the field of thermal energy storage. Porous carbon, with its excellent support, thermal conductivity, and energy storage properties, is considered one of the most promising support matrix materials. However, the simple and efficient synthesis of high-performance and highly active bio-based materials under mild conditions still faces challenges. In our work, a novel method for preparing new functional composite phase-change materials based on enzyme treatment technology and using waste walnut green husk biomass and polyethylene glycol as raw materials was developed. The enzymatic treatment method exposes the internal structure of the walnut green husk, followed by the adjustment of the calcination temperature to increase the adsorption sites of the biochar, thereby stabilizing polyethylene glycol (PEG). The porous properties of walnut green husk biochar effectively regulate the phase-change behavior of polyethylene glycol. In the biochar carbonized at 600 °C, the PEG loading reached 72.09%, and the absorption heat of the solid–solid phase-change material (SSPCM) reached 194.76 J g−1. This work not only enriches the application of biomass in heat storage but also demonstrates the broad prospects of SSPCMs in solar thermal utilization.

“…Integration of nanoadditives (e.g., graphene, metal nanoparticles) can advance the thermophysical properties. In this regard, Zhao et al [125] constructed an aligned carbon fiber-based paraffin composite with high thermal conductivity of 7.38 (axial) and 4.04 W K −1 m −1 (lateral), where the carbon fiber was prepared by attaching graphite flakes to biomass, woven cotton, and carbonization. In fact, the enthalpy of the composite derived without graphite was reduced from 181.0 to 157.2 kJ kg −1 .…”

High‐value‐added biomass materials like biocarbon are being actively pursued integrating them with soft materials in a broad range of advanced renewable energy technologies owing to their advantages, such as lightweight, relatively low‐cost, diverse structural engineering applications, and high energy storage potential. Consequently, the hybrid integration of soft and biomass‐derived materials shall store energy to mitigate intermittency issues, primarily through enthalpy storage during phase change. This paper introduces the recent advances in the development of natural biomaterial‐derived carbon materials in soft material assembly and its applications in multidirectional renewable energy storage. Various emerging biocarbon materials (biochar, carbon fiber, graphene, nanoporous carbon nanosheets (2D), and carbon aerogel) with intrinsic structures and engineered designs for enhanced enthalpy storage and multimodal applications are discussed. The fundamental design approaches, working mechanisms, and feature applications, such as including thermal management and electromagnetic interference shielding, sensors, flexible electronics and transparent nanopaper, and environmental applications of biocarbon‐based soft material composites are highlighted. Furthermore, the challenges and potential opportunities of biocarbon‐based composites are identified, and prospects in biomaterial‐based soft materials composites are presented.
